Tilt Table Tests
A tilt table test is a test used to document changes in blood pressure and heart rate for patients with Myalgic Encephalomyelitis and Chronic Fatigue Syndrome. Some readers report that beta blockers or other medications can interfere with the test results. Here’s how Iris Took a Tilt Table Test
Some people who cannot get a tilt table test, instead try the NASA Lean Test (a “poor man’s tilt table test”). It does not require special equipment and any doctor can do it if they are willing. Some people have had success printing out the form and instructions, bringing it to their doctor, and requesting a special appointment to perform the test.
The CPET is a cardiopulmonary exercise test that is used sometimes used to document impairments in people with Myalgic Encephalomyelitis or Chronic Fatigue Syndrome. The CPET test is used by some people in disability claims. Sometimes this works out great, and sometimes people have regrets. Learn more about the pros and cons of the CPET.
There are several different types of brain scans people have found helpful in documenting ME and related conditions: SPECT and xenon SPECT scans of the brain, PET scans of the brain and EEG/QEEG brain maps. The Hummingbird Foundation Testing for ME explains each of these tests. You can read the short explanations or the long explanations. In some cases, MRIs may be useful though these do not always show results. Some of our readers report that Functional MRIs were more helpful.
There is no specific blood test that is universally recognized as accurately measuring CFS or ME. However, the links at the bottom of this page include many blood tests and other types of medical tests that some patients and doctors have found helpful.
Excluding Other Conditions
Most people test for other conditions before they are diagnosed with ME or CFS. Test results showing other conditions have been excluded can be important documentation. Examples of illnesses that can be ruled out: Addison’s disease, Cushing’s Syndrome, hypothyroidism, hyperthyroidism, iron deficiency, sleep disorders, lupus, Multiple Sclerosis, B12 deficiency, Lyme Disease, and psychiatric disorders.
If you have problems with balance or disequilibrium, a The Romberg Test is a small, simple test your doctor can do in her office anytime. It may not give you a great deal of information, but if you are looking for more documentation on your condition, you can ask your doctor to do a Romberg test and to note the results in your records.
If you think you may also have Lyme Disease, POTS, Fibromylagia or other conditions that are common in ME patients, please check out how to How to Collect Medical Evidence for Other Conditions
